A member of a knife making page on Facebook is selling 20 fire bricks for 150, if anyone is interested
$7.50 sounds rather high to me.
I have 20 or so bricks left over from a Pizza oven build that I’ll let go for $4.00 each…
Ok, just thought I would let y’all know
$3.19 ea at Tractor Supply.
Single Bricks, only about 1.25" thick. For furnaces and ovens thermal mass is a key factor.
